Help!

Hey guys so I’m a nursing student and I work at a hospital so my job can be physical demanding at times, I’m on Ritalin for adhd and stuff I also drink caffeine occasionally should I be concerned if at work my heart rate spikes to 120 I don’t have chest pain or anything but it is high when I’m walking around and working but when I’m in bed it’s normal like 67-82 bpm

Plsss let me know if anyone relates
